Good morning again, Giovanni.

You should add them to the DisegnaPoligonoExtension install method:

public void install( PlugInContext context ) throws Exception {

DelegatingTool delPolygonTool = (DelegatingTool) MyCursorTool.create(context.getWorkbenchContext());
drawPolygonTool = (MyCursorTool) delPolygonTool.getDelegate();
context.getWorkbenchFrame().getToolBar().addCursorTool(drawPolygonTool.getName(),
delPolygonTool, MyCursorTool.createEnableCheck(context.getWorkbenchContext(),drawPolygonTool));

}

Regards,
